I updated LENOVO V570 to win8.1, every thing looks good except the unknown device question mark in device manager.
It looks come from the power manager driver, because in the message center, it is said, power management does not work with a compatabale problem.
I'm using the W540 with an ultradock and external monitors. After upgrading my W540 to win8.1 64 bit, device manager is showing an unknown device. I'm not quite sure what it is, but almost everything seems to be working fine and Lenovo solution center isn't finding any driver updates.
I did notice that the solution center hardware scan did not test the video card memory and listed that test as N/A. Video and monitors seem to be working fine though and both nvidia and intel graphics show up in device manager.
Device manager lists the device in question as follows:
Device instance path: ROOTSYSTEM001
Hardware Ids: rootiwdbus
Device stack: DriverPnPManager
I just bought a B590, model 20208, with, i3-3110m, 500GB HDD, GeForce 720M.I installed Win 7 64bits, but in Device Manager, before installing all the drivers appeared Other Devices an Unknown Device with thise details: code 28, Device type: Other devices; Location: on Microsoft ACPI-Compliant Embedded Controllert . After installing drivers, the problem persists.Another problem was with PCI express but resolved with Intel Management Engine Interface drivers.Other problem resolved was with the GeForce 720 M videocard; wasn't recognized but resolved with the last driver from GeForce site. the last problem remained it's The Unknown Devices.

Windows 8.1 - Installed from scratch.
I was able to install and configure all drivers but one. I found a tread that suggested installing Lenovo Setting Dependency Package 2.0.0.13 to fix it on a different lenovo model. I tried it without any success.
The driver id of unknown driver is "{48126E0D-4BDD-4D26-8A24-569C7AB522D6}SettingsDriver"
Today I found an error in device manager "unknown usb device descriptor request failed" with error code 43. Then I found out webcam doesn't work/disappear. So I try to fix the problem and reset bios setting seem to get it back.
But in windows when I try to use webcam, at first it seem to work normally but after a few minutes it disappear and reappear immediately. Repeating this a few time it was again disappeared with the same "unknown usb device descriptor request failed" error.
Repeating the same bios thing again and it's back, running normally. Then I leave webcam program on(cyberlink youcam) to observe. It working fine for around ten minutes then it was repeating disappear and reappear again and this time it blinking like in this video [URL] .... so I turn off webcam, leave it for minutes and running youcam again and it's back to normal(Still working normally when I post this (working for around 25 minute now)).
What cause this. Does this mean my webcam is failing?
Also my webcam LED indicator flickering rapidly like the light bulb when turn webcam on and stop flickering when I point the bright light to the webcam. Is this normal?
Right after I post this it disappear and reappear again but only one time not repeating.
Now "unknown usb device descriptor request failed" is back and webcam disappear again.
I have just installed Windows 8.1 x64 on my Lenovo E330.
I downloaded drivers from the website, and installed all of them. But after that there's one device listed as Unknown in device manager, and I can't figure our which device it is.
Hardware ID is {48126E0D-4BDD-4D26-8A24-569C7AB522D6}SettingsDriver, so that doesn't identify the device.

How to identify what driver I missed to install
Lenovo V570, I'm on Windows 7 64-bit.
I have an esata port, and was going to get an internal hard drive with a case that converts the drive into an esata drive. I'm wanting to get a 3 TB drive, and in order to get it to read all 3 TB, I'll need to reformat the drive in GPT format (not MBR). Right?
I see a thing online that says the SATA controller has to be compatible with GPT in order to do this. I want to use it as an external drive, without any operating system on it, so I'm not worried about getting Windows to run on it; just if I can format it as GPT and get the full 3 TB out of the drive. I don't want to buy the 3 TB drive and then find out I can only get 2 because of the motherboard. If that site was correct, then I need to know if the sata controller is compatible with GPT.
I see this listed under the IDE ATA/ATAPI controllers list: Intel Mobile Express Chipset SATA AHCI Controller.
I tried to call Lenovo support but could only tell me that she thinks I have SATA 0 or 1, but nothing about the controller in this model or GTP compatibility.
How do I find this out?
I just got a new lenove V570 with Freedos and would like to install Windows 7 professional.
When I try to install Windows 7 64 bit, I get the error: The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks?.
I was wondering if the default Energy Management battery setting of 50% can be changed on the Lenovo V570. I keep the laptop plugged in almost all of the time, and the popup suggests using the setting that keeps the battery at 50% all the time. That's fine in terms of not over stressing the battery, but if I need to unplug the laptop, I'd rather have a fuller charge than only 50%. I'd read that ThinkPads can be set to 90% or other settings. Is that possible with the V570?
View 9 Replies View RelatedSo like many V570 owners I encountered the same problem where the laptop does not turn on anymore. I'm not on warranty anymore so I couldn't send it in to Lenovo either. Based on what I read, this issue appears when the laptop goes to sleep (closing down the lid when the laptop is on, or letting the laptop sleep when you're not using it for a while).
So I was thinking, "Hmm it doesn't make sense to replace the motherboard just because the hard drive is on sleep". Why not just pull out the hard drive and memory cards and put it back in? So I unscrewed the smaller cover on the back of the laptop and unscrewed the hard drive (one screw), pulled out the hard drive (slide it backwards and pull out) and also pulled out the two memory cards (that are on the right side).
Then I simply put the hard drive back in and the memory cards back in place. Screwed the cover back on there and it TURNED ON!
First thing I did after that was go into the Power Options in Windows 7 (just search "Power Options" from the start menu) and went to "Choose what closing the lid does" and changed all the selections that said "Sleep" or "Hibernate" to either "Shutdown or Do Nothing".
NOTE: The down side is that you probably can't Sleep or Hibernate your laptop anymore. I'm trying to see if there's a BIOS update for this but the Lenovo Support website is not loading at the moment.
The UPSIDE is your laptop WORKS and you're not gonna be spending $$$ for an unecessary "motherboard' that they say they'll replace.
what driver is missing for the unknown device with the following specs from the "Device manager"
General
- ACPI-Compliant Embedded Controller
- Drivers not installed error Code 28
device ID
- LEN0068
got every other device running with propper driver (WLAN, Ethernet, USB3.0, Intel Chipset, VCard(both), Touch scanner, Audio, Monitor, Camera, Bluetooth, Cardreader)
I am having 2 problems with networking on my v570. When hard-wire connected to a time warner arris modem, the computer sometimes recognizes the network but does not get internet access.
When connected to an airport extreme via the same modem, it connects to the internet but speeds are drastically low. when I hardwire connect a mac to the modem, it's blazing fast.
Something seems to be wrong with the connectivity [URL] .....
V570 1066 no longer sees 1tb WD Passport HDD in Explorer. it simply lists it as Local drive E: and doesn't allow access. The drive works fine on another laptop.

I reinstalled windows the other day on my V570. Everything is working great except the wireless drivers which i cannot install. In my device manager under other devices, i get an unknown network controller.
I have downloaded and tried installing all of the drivers from the lenovo site as well as tried scanning on the Intel site. i will get the dreaded "no matched wireless" pop up.
I am using Windows 7 home premium which is what came on the machine.
I installed Windows 8 x64 recently and installed all the drivers. I was pretty sure that all the devices were installed.I was having a hardware power management problem before installing Windows 8 that I was hoping was a software issue that reinstalling the OS would fix. Turns out it wasn't software, but had to have the main board replaced under warranty. Even after the main board replacement, I was still pretty sure I saw all the device drivers were installed under device manager.
I'm noticing an "unknown device" listed that doesn't have a driver installed. I know often these can be the TPM or other system device, but I have the TPM installed as well as the chipset software and power management driver. But there is still this unknown device.The only clue I have as to what the device could be is under details, the "hardware ids" property value is "rootsscbfs_storlib_bus3". A Google search brings up nothing for this string. "STORLIB" makes it seem like it has something to do with storage, but I have the Intel RST driver (11.7 from Intel) as well as the card reader driver installed. I can confirm the card reader is functioning fine too.
I have purchased a new E430 ,, installed windows 7 ultimate 64-bit. I installed all drivers and all is working fine.. I still have one unkown device (PCI) .. I think it's VGA .. but I installed intel HD card driver.
below is the info:

I have recently purchased a Lenovo V570 From Best Buy with an i5 2410m and Intel HD 3000. When browsing the web, I came across the option for the V570 to have a dedicated Nvidia 525m Graphics Card.
View 3 Replies View Related I purchased a refurbished V570 for my son. Just received it the other day. Every time it boots up, the System Preparation Tool 3.1.4 boots up. Whenever I turn the laptop off and start it again, instead of showing the regular Windows 7 start up screen, it has a "Setting up your computer for the first time" (or something like that) screen. Once up and running, the tool pops up again. Windows 7 runs perfectly, no issues, I installed a bunch of things for him, but obviously this tool shouldn't be starting up and the laptop shouldn't be starting with the setup screen every time.
I did some digging around the internet, there is a bunch of info on this, but everything indicates that the Windows installation was not properly finished on my laptop. I went to all the places that are listed to possibly remove the tool, but can't find any references except a bunch in the registry which I don't really want to mess with on a "new" computer.
I have an IdeaPad V570 that experienced a total hard drive failure (be careful how hard to close the laptop in frustration) I had Best Buy try to recover data and opted not to pay for the recovery after the only crucial data did not seem to have been recovered. Best Buy told me the rest of the system seems to be intact so they could install a new Hard Drive if I wanted it back. They made me offers to completely restore the system at a price but I decided to save money thinking I should be able to restore the system myself. So they installed the hard drive and that was it.
I decided to go with Windows 8 after learning that support was beginning to wain for Windows 7. I purchased the OS from Best Buy and I am attempting to install it. So far that is not going well. The BIOS sees the CDDVDW drive and the HDD, both are listed in the BOOT menu with the right names. However the computer is not booting from the WIndows disk. I get a message ending with :
PXE-E61: Media test failure, check cable
PXE-M0F: Exiting PXE ROM
At which point it take me to the Boot Menu. I can see the order I have set for Booting is:
1. ATAPI CD: TZSSTcorp CDDVDW TS-L633F
2. ATA HDD: WDC WD10JPVX-22JC3T0
3. PCI LAN: Realtek PXE B03 D00
It seems to me that the system is trying to boot in that order but the CDDVD drive is not responding, the HDD has nothing on it so it goes for the PCI LAN and there is nothing for it to do so it returns the error an sends me back to the Boot Menu.
V570 - works great! Upgraded to Win8 but had probs with it so did a "refresh" and that pretty much cleared it up.Bored so got a Sammy 840Pro SSD. Cloned with stand-alone Acronis Trueimage 2013. Boots and works fine. Had the SSD plugged to the eSATA.Then I noticed that on cold startup, it was not giving me the BIOS options of F2 and F12, and pressing them did nothing - it just booted up Win. Did a lot of googling at this point but no joy.I then noticed that on a restart from Win8 , it DID give me the BIOS options and I could get into the BIOS. But that's a dicey way to run!!! I early on (a year ago) found that you cannot re-order the devices in BIOS - it resets them to what it wants. (latest BIOS 44CN36WW which is 43 - an old one)
Okay, so boot order is SATA port specific, I put my second HD into the primary position and hung the SSD off the eSATA cable. It insisted that the SSD was bootable device 8 (LOL) and tried very hard to boot from the Realtek LAN port. However it WAS giving me the BIOS options so I could hit F12 and choose the SSD and boot into windows. I also found that if I pulled the RJ45 before I hit power, it would try the Realtek, but then bounce to the list of devices - choose the SSD, and boot into windows.I moved the SSD to the DVD port (I had an adapter), but exact same thing - still calls it 8.So it works and is a good deal faster than the original Toshiba drive which did 90MB read. But there is that unfortunate pause in my 10-15 sec win boot!
I was trying to find the Active Protection System software for Win8 for while now, it's just not coming up anywhere. I really need to disable the disc freezing feature on my V570 cause it's super annoying (especially when watching videos).
Whether the software is available? I've tried the Win7 version, but there are some compatibility issues, so it doesn't work....
Also, if the software is not available yet for Win8, are there other ways of turning this thing off (BIOS, registry)???
I just upgraded to windows 8 pro x64 on my Lenovo V570 and it can't find the driver for my built in webcam. My girlfriend is moving away for 6 months starting next week and the webcam is really important for us to stay in touch.

I contacted Dell, they said they won't support my laptop since I don't have their operating system on it. All I want to know is what drivers I need. I can't believe they couldn't let me know.
I have an HP Pavilion dv5-1183cl that has been upgraded from Windows Vista to Windows 7 Ultimate (32bit) and I have some issues.I have four errors showing up in my device manager, three Base System Device and one Unknown Device, and I don't know what they are or where to get the drivers (since I don't know what they are). Additionally, the battery will not charge (there does not appear to be anything wrong with it physically). I am wondering if the below errors are related to the battery issue.

Faced with the problem. No sound after the laptop. When you try to check the sound device, a window pops up "the device is already in use by another application." But no program is not running. After rebooting the laptop sound occurs. Drivers are all set.

UEFI boot mode, not Legacy.Drivers for sound downloaded from realtek.com.tw. With standard windows drivers sound is always there. Tried the previous version of the drivers - ineffectually. Could it be that the problem is due to the UEFI boot mode? I do not want to reinstall the OS mode Legacy just to check it out.
